LDA Mallet CalledProcessError

Question

我正在尝试实现以下代码：

import os
os.environ.update({'MALLET_HOME':r'c:/mallet-2.0.8/'})
mallet_path = 'C:\mallet-2.0.8\bin\mallet'
ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=bow, num_topics=20, id2word=dictionary)

但是，我不断收到此错误：

CalledProcessError： 命令 'C：\mallet-2.0.8\bin\mallet import-file --preserve-case --keep-sequence --remove-stopwords --token-regex "\S+" --input C：\Users\Joshua\AppData\Local\Temp\98094d_corpus.txt --output C：\Users\Joshua\AppData\Local\Temp\98094d_corpus.mallet' 返回非零退出状态 1。

我以前能够在具有相同目录的笔记本电脑上执行此代码，但它无法在我的 PC(我当前运行 python(上执行。

有人可以让我知道我做错了什么吗？

我遇到了类似的错误。 仔细检查您是否安装了 java 以及文件路径是否正在调用 java。 我不得不像这样编辑在 mallet 文件夹 C：\mallet\mallet-2.0.8\bin 中找到的 mallet.bat 文件：

@echo off
rem This batch file serves as a wrapper for several
rem  MALLET command line tools.
if not "%MALLET_HOME%" == "" goto gotMalletHome
echo MALLET requires an environment variable MALLET_HOME.
goto :eof
:gotMalletHome
set MALLET_CLASSPATH=C:malletmallet-2.0.8class;C:malletmallet-2.0.8libmallet-deps.jar
set MALLET_MEMORY=1G

shift

echo Mallet 2.0 commands:

echo   import-svmlight   load a single SVMLight format data file into mallet instances (one per line)

echo   train-classifier  train a classifier from Mallet data files

echo   split             divide data into testing, training, and validation portions
echo   bulk-load         for big input files, efficiently prune vocabulary and import docs
echo Include --help with any option for more information
goto :eof
:gotClass
set MALLET_ARGS=
:getArg
if "%1"=="" goto run
set MALLET_ARGS=%MALLET_ARGS% %1
shift
goto getArg
:run
"C:Program FilesJavajdk-12binjava" -ea -Dfile.encoding=%MALLET_ENCODING% -classpath %MALLET_CLASSPATH% %CLASS% %MALLET_ARGS%
:eof

然后更改文件路径以反映此更改：

mallet_path = 'C:/mallet/mallet-2.0.8/bin/mallet.bat'

希望这对:)有所帮助
